I call this machine the "pantorouter" because it's essentially a big pantograph mechanism with a router in it. It's used to route shapes from 2x sized templates. I originally designed it for cutting tenons, but the machine is very versatile and can be used for all kinds of wood joints.
I invented and published this machine in 2010. In 2014, I built the Pantorouter XL, which is designed to accommodate plunge routers.
In 2018, I revised the design, adding a vertically adjustable template
holder, moving the depth stops to the side, and a few minor changes
to make it easier to build. This time, I filmed the whole construction.
